Bulldozer Rampage In Granby, June 4, 2004

June 4, 2004, was the date of Marvin Heemayer's rampage through the town of Granby with an armored bulldozer. The Komatsu D355-A with a 410-horsepower engine destroyed or damaged 12 buildings and caused $5 million damage. CBS4's Copter4 helicopter was the only news helicopter to fly over Granby while the rampage was going on. Granby is a mountain town of 1,600 residents. Heemeyer rammed the 20-cubic-yard blade of his "MK Tank" into several town buildings, including the municipal center. Every round that SWAT teams and police fired at Marvin Heemeyer did little more than pockmark the steel-plated covering of the bulldozer. Heemayer killed himself inside the bulldozer after the 90 minute rampage came to a stop. The bulldozer was towed out of Granby and eventually dismantled. (image credit: CBS)

Bulldozer Rampage In Granby, June 4, 2004

To make the bulldozer, Marvin Heemeyer (not pictured) poured 4 inches of concrete between plates of steel, which he welded onto the Komatsu to armor it. Heemeyer rigged the bulldozer with video cameras equipped with air compressors to blow dust off the lenses. Images of the world outside appeared on monitors inside the enclosed cab so he could guide it without exposing himself, according to the Rocky Mountain News. He stuck three guns, including a .50-caliber rifle, out of portholes bored into the armor to keep authorities at bay. The Komatsu D355-A bulldozer had a 410-horsepower bulldozer engine and it was primed, fueled and protected by steel and concrete. It destroyed or damaged 12 buildings and caused $5 million damage.

Bulldozer Rampage In Granby, June 4, 2004

June 4, 2004, was the date of Marvin Heemayer's rampage through the town of Granby with an armored bulldozer. The Komatsu D355-A with a 410-horsepower engine destroyed or damaged 12 buildings and caused $5 million damage. CBS4's Copter4 helicopter was the only news helicopter to fly over Granby while the rampage was going on. Granby is a mountain town of 1,600 residents. Heemeyer rammed the 20-cubic-yard blade of his "MK Tank" into several town buildings, including the municipal center. Every round that SWAT teams and police fired at Marvin Heemeyer did little more than pockmark the steel-plated covering of the bulldozer. Heemayer killed himself inside the bulldozer after the 90 minute rampage came to a stop. The bulldozer was towed out of Granby and eventually dismantled. (image credit: CBS)
